I removed the horn button and shot a couple pics for interested viewing.
Remember, this is not a production part, this is the proto type.
This is a shot of everything separated. I noticed I am short one 6/32" countersunk screw.
This is a shot of the inside assembled.
This shot show how you can separate the center section and customize it however you like. It could be painted car color, black, rubberized, carbon fibered whatever.
Cheers!
